Three colloquia opportunities in the next two weeks
Abstract: High Performance Computing refers to the aggregation of resources (compute, data, interconnects) to deliver the significant computational power for large-scale problems. Current systems have hundreds of thousands of resources. For example, the Theta supercomputer at Argonne National Laboratory consists of 4,392 nodes, each containing a 64 core Xeon Phi processor, resulting in 281,088 cores. Such machines are used to solve large-scale applications in physics or engineering, for which it is important to analyze the performance of the applications to achieve efficient execution. This talk will provide an overview of HPC systems, motivate the need for performance analysis and modeling, and present some research results from the use of the models to improve performance.
Abstract: The demand for computational power continues to drive the deployment of ever-growing parallel systems. Production parallel systems with hundreds of thousands of components are being designed and deployed. Future parallel systems are expected to have millions of processors and hundreds of millions of cores, with power requirements. The complexity of these systems is increasing, with hierarchically configured manycore processors and accelerators, together with a deep and complex memory hierarchy. As a result of the complexity, applications face an enormous challenge in exploiting the necessary parameters for efficient execution. While reducing execution time is still the major objective for high performance computing, future systems and applications will have additional power requirements that represent a multidimensional tuning challenge. To embrace these key challenges, we must understand the complicated tradeoffs among runtime and power, and in some cases resilience strategies. This talk will present our methods and analyses to explore these tradeoffs for parallel applications.
Abstract: Can a mathematician be a Christian? Can a Christian student do math? No matter, come discover from the owner of Elvis, the dog who knew calculus, himself a preacher’s kid of deep and intriguing connections between mathematics and theology. Why did the Apostle Paul write, “If the dead are not raised, then Christ is not raised . . ” What is the logical error in the Apostles’ Creed? What do differential equations reveal about the problem of evil? What does “e” have to do with moral dilemmas? How do prime numbers illustrate moral absolutes? How does Cantor’s infinity justify the notion of the Trinity? If intrigued – be there.

Become a MathPath Counselor this summer
MathPath is an advanced summer program in mathematics for kids 11-14 years old. This summer it will be held at Grand Valley State University and they are looking for counselors. In particular they don’t currently have enough male counselor applicants to fill their spots and are accepting late applications. Interested students would need to submit applications as soon as possible. Graduating seniors are included in “current undergraduate students.”
